IN NUT-LOCKING DEVICE.

m l 'he Schedule referred to these Letters-,Patent andrmakjng parl: of the same.

To allrwhom tmc/y concern:

Be it known that I, P. PHJLHPL of Beardstown, in thecounty of Cass, and State'of Illinois, have invented a new and useful Improved Nut-Locking Device; and I do hereby declare that the following is a full, clear, and exact description thereof; which will enable others .skilled 'in the art to'make and use the same, reference being had to the accompanying. drawing, forming part of this specification. v-

This invention relates to improvements in nut-locking devices, for preventing the nuts' from becoming loose upon fastening-bolts, and designed more particularly for locking the nuts of bolts used for fastening fish-plates. v v

It consists of a bar, having mortises through it, or notches in the ends or sides, to fit 4the nuts, to be placed on the surface ofthe fish-plate against which the nuts are screwed, seas to engage the nutsv in the said notches,

or mortises, and, being held in said position by a bolt or bolts projectingY from the said surface, and held by spring-keys, thereby locking the said nuts, and preventing their disengagement.

Figure 1 represents a plan view of my improved device; and

Figure 2 represents a longitudinal sectional elevation I of the same. v Y

Similar letters of reference' indicate like parts. A represents the locking-plate, which may have mortises t through it, of the form ofthe nuts b, to be secured; or, instead of the mortises, notches may be formed in the end of the plate, to lit a corner of the nut, or of suiicient size to envelop half 'the nut.

The said plate is placed upon the fish-plate, or other thing to the bolts of which the nuts are to be looked, p so as to'enter the said nuts in the mortises or notches, as represented in g.1, and may be held in that position by a bolt C, having a spring-pin, or key to hold it.

In case there is but one nut to be held, and the plate A has only a notch in the end, dowel-pins, d, may be fixed in the fish-plate, or other article, to take into holes in the plate A, to prevent it from turning on the bolt C, so as to disengage the nut.

I am' aware that bars have been used, having notches in their sides adapted to [it against shoulders formed upon the under side or" the nuts; but this I do not claim.

What I do claim, and desire to secure by Letters, Patent, is l Y The notched plate A, when secured to the fish-plate by means ofthe bolt C, the spring-key, and the dewel-4 pins d, as herein described, for the purpose specified. Y P. PHILIPPI. Witnesses:
